Abstract: An alignment and retention device (10) for optical transmission fibers having an optical lens (44) with a forwardly directed curved surface (46) molded to a rearward extension (50). The extension has an upper portion (52) and a lower portion (54) separated by a vee-shaped gap (108), each portion having a longitudinally extending vee-shaped groove (104,106) for aligning and supporting an optical fiber (64). The lens and rearward extension are fashioned from a single piece of plastic with an abutment means (58) comprised of a vertical stop (60) at an interface therebetween. A focal point of the lens is located at the abutment means and a retention means (70) securely retains the optical lens while a clamping means (72) surrounds the retention means forcing the upper and lower portions together for capturing the optical fiber within the vee-shaped gap providing forward an lateral fiber alignment without using an index matching adhesive.

The manipulating section includes at least a rhythm selecting switch (7) for selecting a rhythm kind and a tempo speed control switch (9a, 9b) which controls the tempo clock generator to thereby change a tempo speed. The pattern memory stores a plurality of tone data (TONE) each representative of a tone color and a plurality of pattern data (PAT) each representative of a performance pattern. The tempo speed is divided into three speed areas. The tone data and pattern data are sequentially read from the pattern memory based on the selected rhythm kind and each speed area. Based on such read tone data and pattern data, the tone generator generates a musical tone signal by which desirable musical tones are to be generated.

Abstract: As a rule, concrete palisades have hitherto been manufactured in modified pipe-moulding machines. In this process, the production cost for manufacturing a range of concrete palisades of different length is considerable. With the novel process and corresponding apparatus, the intention is to be able to manufacture the novel concrete palisade at a substantially lower cost. The concrete palisade is manufactured from a moulded concrete article (23) which has the same configuration as the concrete palisade. Several moulded concrete articles are produced simultaneously in a brick-moulding machine known per se and are also provided there with predetermined breaking points (25, 30). Finally, one or more concrete palisades of the same or different length can be manufactured from a moulded concrete article by breaking at one or more predetermined breaking points. The particular configuration of the concrete palisade permits inexpensive production of concrete palisades in conventional brick-moulding machines.

Abstract: A heat pump system has a refrigerant circulation system that is cooled by passing through a thermal storage heat exchanger. The heat exchanger is supplied by ice from an ice maker and can store heat energy by accumulation of ice in the heat exchanger. The ice is generated by cooling a secondary refrigerant, typically brine, at the wall of a ice making machine and scouring the wall prior to crystallisation of the brine mixture to disperse the super cooled liquid adjacent the wall into the body of the secondary refrigerant. Crystallisation is then promoted in the body of the liquid. The ice generator in a preferred form comprises a series of flat plates having primary refrigerant passing between the flat plates and secondary refrigerant passing over the surface of the flat plates. A series of scrapers rotate about an axis normal to the plane of the plates to disperse super cooled secondary refrigerants throughout the body of the secondary refrigerant in the ice generator.

Abstract: Methods and apparatus for administering known quantities of medicament by iontophoresis, while avoiding burns caused by extremes in the pH of the medicament medium during passage of an electric current, are disclosed. In conventional iontophoresis systems, due to the occurrence of electrolysis of water extreme changes in pH are experienced which result in burns due to the acidification or alkalinization of the medicament medium and passage of electric current through the skin. In addition, the efficiency of iontophoresis decreases over time. The present invention avoids extremes in pH by removing the hydrogen or hydroxyl ions which are created during iontophoresis and creates conditions for constant delivery over prolonged periods of time. 
     In the present invention, the medicament ions are attached to an ion exchange matrix, such as an ion exchange resin. When the medicament leaves the ion exchange matrix, the vacated active site is filled by the produced electrolysis products, thereby allowing iontophoresis to progress at a relatively constant pH.

Abstract: A thyristor having a main cathode 1 and an anode electrode 2 between which conduction occurs, also includes a region of long charge carrier lifetime 12. During forward conduction between the cathode 1 and anode 2, carriers diffuse into the region of long lifetime region 12. If, during reverse recovery, but prior to the thyristor recovery time, a positive going voltage ramp is applied across the device, turn-on is initiated in the long lifetime region 12 due to the presence of unrecombined charge and displacement currents generated. The current produced is limited by resistors 9 and 17 to prevent damaging high levels and is used to switch on the remainder of the thyristor (via an amplifying gate) without any damage to the device occurring. In previous thyristors not including a region of long carrier lifetime, such a voltage might result in turn-on occurring over only a very small volume and the heat dissipated could destroy the thyristor.
